Improvement in railway-carriages



UNITED STATES NAHUM FRANKLIN BRYANT, OF EAST BOSTON, MASSACHUSETTS.

iMPROVENl ENT lN RAILWAY-CARRIAOES.

Specification forming part of Letters Patent No. 40,@ B 3, dated December 8, ISGS.

To' all whom it may concern:

Be itknown that I, NAHUM FRANKLiN BRY- ANT, a resident of East Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements having reference to Railway-Carriages; and I do hereby declare the same to be fully described in the following specification, and represented in the accompanying drawings, of which- Figure l denotes a side`elevation, Fig. 2 a vertical and longitudinal section, and Fig. 3 a vertical and transverse section, of my invention, this latter section being taken through the chock, to be hereinafter described. Fig. 4

is a horizontalsection of such invention. Fig.

5 is a side view, and Fig. 6 an edge view, of the chock. Fig. 7 is a top view of the removable* chock-stopper, which answers as a bottom for the chock-chamber of the housing.

My present invention has reference and is auxiliary to that for which Letters PatentNo. 39,545 were grantedA to me on the 18th day of August, A. D. 1863, the design or'pnrpose of the invention so patented being to enable a railway-carriage to be run upon either of l two or more railway-tracks of different gages,

as well as from, to, or upon the other, as circumstances may require.

In the drawings, c denotes a wheel-axle as provided with a sliding box, e, which slides endwise within a housing, f, which, when lin use, is bolted or 'fastened to the frame of a railway-carriage, stands vertically, and is open at bottom except in being provided with a removable stopper, a, which not only serves to close the open part or mouth of the housing, so as to prevent the entrance of dust or extraneous matters into the housing, but operates tol support the chock when at its lowest position and keeps it in connection with the housing.

The .stopper t is formed as shown in top View in Fig.' 7, and when in place it embraces the two portions h h of the chock, and is supported on two bolts, it, which go horizontally through the housing, as shown in the` drawings.

The chock H, formed as represented in the drawings, slides vertically within the housing, and is for the purpose of cstopping the sliding box of the wheel-axle from longitudinal motionin a direction into or toward the housing whenever the said chock 'may beat its lowest position. While the chock may be at its highest elevation its recess or` opening k will allow the box to-slide into or through the chock and up to an opening, Z, made through the front of the housing and'provided with a closing-plate, m. It is through the opening Z that -access may be had to the interior 'of the sliding axle-box, either for the purpose of supplying its oil-chamber with lubricating material or for effecting the insertion or the removal of the journal with respect to the box.

. Ihe sliding box is hollow or/furnished with a chambery-n, into which the journal o of the axle projects, and is held therein not only by a partition, p, extending across the chamber and partially around the journal, but by a flange or head, q, formed on the journal. There is also within the chamber n a movable composition bearing, i', whichis supported against a wedge, s, which on being withdrawn from the box enables the bearing to be lifted within and removed from the box. The housing is also made with a packing-groove, t, to contain packing u to encompass the external surface of the sliding box, such groove and packing being to prevent the access of dirt or dust into the housing, as well as to cause the box during its movements to operate with little or no friction against the inner surfaces of the housing. y Furthermore, there extends down from the housing a projection or lip, s', which I term the centralizer, its purpose being to maintain the truck frame or carriage at its proper position with respect to the rails while the wheels of opposite sides of the truck may be in the act of being moved either toward or apart from one another.

In my said patent I preferred to confine my invention to one subject, as indicated by the claim thereof, intending to explain and claim in a separate application for a patent what might be auxiliary to my main invention. I would remark', however, that I am aware that, although the sliding box, its housing, and axle, as combined and arranged in manner as herein described are new or of' my invention, and also the combination of the same and the chock to be used in manner and for the purpose described is new with me and of my invention, I am also aware that it is not new to make the stationary box of a railway-carriage axle hollow or with an oi1-chamber and a mov- `to operate with them ,substantiall y as specified.

3. The combination of the movable stopper c with the housing f and its chock H, the said stopper being for the purposes or to operate as specied.

4. The housngas made or provided with the packing-groove t and packing u, to encompass the sliding box, in manner and for the purposes specified. l

5. The combination of the centralizer or lip s with the housing or truck frame or carriage thereof, when the latter has its wheels soapplied as to be capable of being adjusted by means of a wheel-changing `track to either of two tracks of di'erent gages.

NAHUM F. BRYANT.'
